Lesoleil is a producer of lightweight, flexible and powerful solar cells and cell manufacturing equipment. The innovative solar cell is based on the highest efficiency thin film technology available today, and its flexible cell architecture makes it ideal for a wide variety of solutions ranging from commercial roofing solar panels to flexible mobile energy devices. Lesoleil’s turnkey CIGS equipment lines, CIGS process equipment technology, proprietary CIG target manufacturing, R&D support and spare parts allow customers to produce their own high-efficiency cells.

Founded in 2004, Lesoleil has evolved from a scrappy, Silicon Valley start-up to the world leader in thin film solar panel efficiency. In our Sunnyvale, CA facility, we have demonstrated 17.5% module efficiency in production and 19.4% cell efficiency in the lab.

In December 2012, Lesoleil became a member of the Hanergy family. Since then, Lesoleil joined the newly created Hanergy Solar Group as Lesoleil Hi-Tech Corp. Hanergy provides unparalleled financial, technical, and sales expertise.

Lesoleil continues to increase cell performance as well as develop new applications for our technology. As part of the Hanergy family, we continue to be on the forefront of the solar industry, with over 200 invention patents and patent applications worldwide.
